Definitions
- the present disclosure provides compounds as well as their pharmaceutical compositions that modulate the activity of PI3Ka and are useful in the treatment of various diseases related to PI3Ka, including cancer.
- PI3Ks phosphoinositide 3-kinases
- PI3Ks belong to a lipid kinase family which catalyzes the phosphorylation of lipids contained in or associated with cell membranes.
- the PI3K family has fifteen kinases with distinct substrates, expression pattern, and modes of regulation.
- the class-I PI3Ks (pl 10a, pl 10p, pl 105, and pl 10y) are typically activated by tyrosine receptor kinases or G-protein coupled receptors to generate PIP3, which activates downstream effectors of Akt, mTOR, or Rho GTPases (Fruman et al., Nat. Rev. Drug Discov., 2014, 13(2), 140-156).
- Genetic mutations in the gene coding for PI3Ka are hotspot point mutations within helical and kinase domains, such as E542K, E545K and H1047R. These mutations have been observed to occur in many cancer types such as lung, stomach, endometrial, ovarian, bladder, breast, colon, brain, prostate, and skin cancers. Because these gain-of-function mutations in PI3Ka are associated with tumor progression, targeting this pathway may provide valuable therapeutic opportunities (Courtney et al., J. Clin. Oncol., 2010, 28 (6), 1075-1083).
- PI3Ks While multiple inhibitors of PI3Ks have been developed (for example, taselisib, alpelisib, buparlisib and others), these molecules inhibit multiple PI3K isoforms. These “pan-PI3K” inhibitors have encountered major hurdle in the clinical development due to inability to achieve the required level of target inhibition in tumors while avoiding toxicity in cancer patients (Fruman et al., Nat. Rev. Drug Discov., 2014, 13(2), 140-156). The toxicity of PI3K inhibitors is dependent on their isoform selectivity profde.
- PI3Ka Inhibition of PI3Ka is associated with hyperglycemia and rash, while inhibition of PI3K5 or PI3Ky is associated with diarrhea, myelosuppression, and transaminitis (Hanker et al., Cancer Discov., 2019, 9(4), 482-491). Therefore, selective inhibitors of PI3Ka may increase the therapeutic window, enabling sufficient target inhibition in the tumor while avoiding dose -limiting toxicity in cancer patients.
- PI3Ka selective inhibitors which are equally potent to wild-type and mutant PI3Ka, often cause hyperglycemia and/or hyperinsulinemia (Busaidy et al., J. Clin. Oncol., 2012, 30, 2919-2928).
- developing inhibitors with enhanced selectivity for mutant PI3Ka against wild-type PI3Ka would be able to overcome the problem of compensatory insulin production and hyperglycemia.
- the present disclosure provides compounds and/or compositions useful for inhibiting PI3Ka.
- provided compounds and/or compositions are useful for selectively inhibiting PI3Ka over other PI3K isoforms.
- provided compounds and/or compositions are useful for selectively inhibiting mutant PI3Ka over wide- type PI3Ka.
- provided compounds and/or compositions are useful, among other things, treating and/or preventing diseases, disorders, or conditions associated with PI3Ka.
- provided compounds and/or compositions are useful, among other things, treating and/or preventing diseases, disorders, or conditions associated with mutant PI3Ka.
- the present disclosure provides certain compounds and/or compositions that are useful in medicine, and particularly for treating cancer.
- the present disclosure provides a compound of Formula I:
- provided compounds have structures of any of Formulae II, III, IV, V, Va, VI, Via, VII, Vila, and Vllb as described herein.
- provided compounds have structures of any of Formulae II, III, IV, V, Va, VI, and Via as described herein.
- the present disclosure provides compositions that comprise and/or deliver a provided compound.
- such compositions are pharmaceutical compositions comprising a pharmaceutically acceptable carrier.
- the present disclosure further provides methods of inhibiting PI3Ka activity, comprising contacting the PI3Ka with a compound described herein, or a pharmaceutically acceptable salt thereof.
- the present disclosure further provides methods of treating a disease or a disorder associated with PI3Ka in a patient by administering to the patient a therapeutically effective amount of a compound of the disclosure, or a pharmaceutically acceptable salt thereof.
- the present disclosure further provides a compound described herein, or a pharmaceutically acceptable salt thereof, for use in any of the methods described herein.
- the present disclosure further provides use of a compound described herein, or a pharmaceutically acceptable salt thereof, for the preparation of a medicament for use in any of the methods described herein.

- R and S configurations of each stereocenter are contemplated as part of the disclosure. Therefore, single stereochemical isomers, as well as enantiomeric, diastereomic, and geometric (or conformational) mixtures of provided compounds are within the scope of the disclosure.
- Table 1 shows one or more stereoisomers of a compound, and unless otherwise indicated, represents each stereoisomer alone and/or as a mixture.
- isotopically-labeled compounds may have one or more atoms replaced by an atom having an atomic mass or mass number usually found in nature.
- isotopes present in compounds of the present disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as, but not limited to, 2 H, 3 H, 13 C, 14 C, 15 N, 17 O, 18 O, 35 S and 18 F.
- Certain isotopically-labeled compounds of the present disclosure in addition to being useful as therapeutic agents, are also useful in drug and/or substrate tissue distribution assays, as analytical tools or as probes in other biological assays.
- tritiated (e.g., 3 H) and carbon-14 (e.g., 14 C) isotopes are useful given their ease of detectability.
- replacement of one or more hydrogen atoms with heavier isotopes such as deuterium, (e.g., 2 H) can afford certain therapeutic advantages.
- a bivalent carbocycle is “carbocyclylene”, a bivalent aryl ring is “arylene”, a bivalent benzene ring is “phenylene”, a bivalent heterocycle is “heterocyclylene”, a bivalent heteroaryl ring is “heteroarylene”, a bivalent alkyl chain is “alkylene”, a bivalent alkenyl chain is “alkenylene”, a bivalent alkynyl chain is “alkynylene”, and so forth.

Abstract
The present disclosure provides compounds, compositions, and methods useful for inhibiting PI3Kα, and/or treating a disease, disorder, or condition associated with PI3Kα, and/or treating cancer.
Description
PI3Ka INHIBITORS
TECHNICAL FIELD
The present disclosure provides compounds as well as their pharmaceutical compositions that modulate the activity of PI3Ka and are useful in the treatment of various diseases related to PI3Ka, including cancer.
BACKGROUND
In the past few decades, signal transduction events have been studied to demonstrate critical roles in regulating almost all aspects of biological responses. Aberrant activation of the signaling pathways regulating cell survival and proliferation is commonly observed in many human cancers. The phosphoinositide 3-kinases (PI3Ks) signaling pathway is documented to be one of the highly mutated pathways in human cancers (Vogelstein et al., Science, 2013, 339(6127), 1546-1558). The PI3K signaling pathway regulates cell survival and proliferation. Increased activity of this pathway is associated with tumor progression and resistance to cancer therapies (Fusco et al., Front Oncol., 2021, 11, 644737).
PI3Ks belong to a lipid kinase family which catalyzes the phosphorylation of lipids contained in or associated with cell membranes. The PI3K family has fifteen kinases with distinct substrates, expression pattern, and modes of regulation. The class-I PI3Ks (pl 10a, pl 10p, pl 105, and pl 10y) are typically activated by tyrosine receptor kinases or G-protein coupled receptors to generate PIP3, which activates downstream effectors of Akt, mTOR, or Rho GTPases (Fruman et al., Nat. Rev. Drug Discov., 2014, 13(2), 140-156).
Genetic mutations in the gene coding for PI3Ka are hotspot point mutations within helical and kinase domains, such as E542K, E545K and H1047R. These mutations have been observed to occur in many cancer types such as lung, stomach, endometrial, ovarian, bladder, breast, colon, brain, prostate, and skin cancers. Because these gain-of-function mutations in PI3Ka are associated with tumor progression, targeting this pathway may provide valuable therapeutic opportunities (Courtney et al., J. Clin. Oncol., 2010, 28 (6), 1075-1083). While multiple inhibitors of PI3Ks have been developed (for example, taselisib, alpelisib, buparlisib and others), these molecules inhibit multiple PI3K isoforms. These “pan-PI3K” inhibitors have encountered major hurdle in the clinical development due to inability to achieve the required level of target inhibition in tumors while avoiding toxicity in cancer patients (Fruman et al., Nat. Rev. Drug Discov., 2014, 13(2), 140-156). The toxicity of PI3K inhibitors is dependent on their isoform selectivity profde. Inhibition of PI3Ka is associated with hyperglycemia and rash, while inhibition of PI3K5 or PI3Ky is associated with diarrhea,
myelosuppression, and transaminitis (Hanker et al., Cancer Discov., 2019, 9(4), 482-491). Therefore, selective inhibitors of PI3Ka may increase the therapeutic window, enabling sufficient target inhibition in the tumor while avoiding dose -limiting toxicity in cancer patients. However, given the central role of PI3Ka in regulating glucose homeostasis and other critical physiological process, current PI3Ka selective inhibitors, which are equally potent to wild-type and mutant PI3Ka, often cause hyperglycemia and/or hyperinsulinemia (Busaidy et al., J. Clin. Oncol., 2012, 30, 2919-2928). In summary, developing inhibitors with enhanced selectivity for mutant PI3Ka against wild-type PI3Ka would be able to overcome the problem of compensatory insulin production and hyperglycemia.

Labeled Compounds and Assay Methods
Another aspect of the present invention relates to fluorescent dye, spin label, heavy metal or radio-labeled compounds of the invention that would be useful not only in imaging but also in assays, both in vitro and in vivo, for localizing and quantitating the PI3Ka enzyme in tissue samples, including human, and for identifying PI3Ka enzyme ligands by inhibition binding of a labeled compound. Accordingly, the present invention includes PI3Ka enzyme assays that contain such labeled compounds.
The present invention further includes isotopically -labeled compounds of the invention. An “isotopically” or “radio -labeled” compound is a compound of the invention where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (z. e. , naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present invention include but are not limited to 2H (also written as D for deuterium), 3H (also written as T for tritium), nC, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 18F, 35S, 36C1, 82Br, 75Br, 76Br, 77Br, 1231, 1241, 125I and 131I. The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro FGFR enzyme labeling and competition assays, compounds that incorporate 3H, 14C, 82Br, 1251 , 131I, or 35S will generally be most useful. For radio-imaging applications nC, 18F, 125I, 123I, 124I, 1311, 75Br, 76Br or 77Br will generally be most useful.
One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, one or more atoms are replaced or substituted by deuterium. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a C1-6 alkyl group of Formula I can be optionally substituted with deuterium atoms, such as -CD3 being substituted for -CH3). In some embodiments, alkyl groups of the disclosed Formulas (e.g., the compound of any of Formulas I-VIIb) can be perdeuterated.
In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-VIIb), or a pharmaceutically acceptable salt thereof, comprises at least one deuterium atom.
In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-VIIb), or a pharmaceutically acceptable salt thereof, comprises two or more deuterium atoms.
In some embodiments, the compound provided herein (e.g., the compound of any of Formulas I-VIIb), or a pharmaceutically acceptable salt thereof, comprises three or more deuterium atoms.
In some embodiments, for a compound provided herein (e.g., the compound of any of Formulas I-VIIb), or a pharmaceutically acceptable salt thereof, all of the hydrogen atoms are replaced by deuterium atoms (z.e., the compound is “perdeuterated”).
It is understood that a “radio-labeled ” or “labeled compound” is a compound that has incorporated at least one radionuclide. In some embodiments the radionuclide is selected from the group consisting of 3H, 14C, 1251 , 35S and 82Br.
Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, N.Y., Appleton-Century-Crofts, 1971; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of Chemistry, 2011). Isotopically labeled compounds can be used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays.
Substitution with heavier isotopes, such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances, (see e.g., A. Kerekes et. al. J. Med. Chem. 2011, 54, 201-210; R. Xu et. al. J. Label Compd. Radiopharm. 2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages.
A radio-labeled compound of the invention can be used in a screening assay to identify/evaluate compounds. In general terms, a newly synthesized or identified compound (i.e., test compound) can be evaluated for its ability to reduce binding of the radio-labeled compound of the invention to the PI3Ka enzyme. Accordingly, the ability of a test compound to compete with the radio-labeled compound for binding to the PI3Ka enzyme directly correlates to its binding affinity.
Kits
The present invention also includes pharmaceutical kits useful, for example, in the treatment or prevention of PI3Ka-associated diseases or disorders referred to herein which
include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of the invention. Such kits can further include, if desired, one or more of various conventional pharmaceutical kit components, such as, for example, containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit.
The invention will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the invention in any manner. Those of skill in the art will readily recognize a variety of non- critical parameters which can be changed or modified to yield essentially the same results. The compounds of the Examples were found to be inhibitors of PI3Ka as described below.
